Application filed J1i1y'8, 1912. Serial No. 708,-226.

T 0 allwiiom it may concern? Be it known that I; Hnnnnn'r Hunrine DONDAvIsoN, of the city of Winnipeg; 1n the Province of Manitoba, Canadahave invented certain new and useful Improve ments in sheaf-Loaders, ofwhich the following is a specification.

My invention relates to a device for load-- ing sheaves and the objectof the invention is topro'vide a-machine embodying a drlven adjustableelevator and a dumpiraok wherein the sheaves are picked up and elevatedby the elevator or oonveyer and deposited into the dump rack, the lowerend of thesupported forwardly on caster wheelsand rearwardly ontractorwheels, a dump rack mounted on the frame to the rear, an "inclined' elevator or conveyer carried bythe frame and having the upperand lower ends thereof adjustable, and' means for driving the elevator,the parts being arran ed and constructed as hereinafter moreparticularly described.

Figure 1 is a side view of the machine; Fig. 2 1s a front' v ew thereof;Fig-3 1s an enlarged detailed longitudinal sectional view through theelevator andadjoining parts; Fig. 4 is an enlarged detailed seotionalviewthrough the machine; the sec+ tio-n being taken in theplane denotedby the line X X, Fig. 2. Fig. 5 is an enlarged detailed sectional viewthrough the machine, the section being taken in the plane denoted by theline Y Y, Fig; 2; Fig.6 is an enlarged detailed front elevation of theclutch member of the back: axle. Fig. 7 is an enlarged detailed endelevation of the inner clutch member, the wheel and. outer clutch memberbeing removed from the. axle.

In the drawings like characters of reference indicate correspondingparts in each figure.

1 represents a substantially rectangular main frame formed from sidebeams 2and 3 and an end beam 1, which frame is car ried rearwardly by anaXle 5 on'whiclr I have: mounted rotatable traction: wheels 6, and-issupported forwardly by two standards? and 8" supplied at the lower endwith caster wheels 9. V

10 is an arched oryoke-shaped rodspa-nning the forward or open end ofthe frame.

11: and 12 are two inclined angle iron bars secured permanently at theirlowerends to the beams 1 and 2 and at their'upper ends totwo uprights'13secured to the main frame. i p

' 1 1' and 1am afurt-her pair of angle iron bars hinged atloto thelowerends of the bars 11 and" 12 andforming in! reality a hinged oradjustable lower extension of such bars.

17 is a cross shaft rotatably mounted in the: lower ends of thebjars 14and '15 and having the-ends extending there beyond and entering slots.18 formed in the stand ar'ds 7 and 8, which slots it will-be noticedare arched; thecenter" point'of the arch being at the hinge16. Theendsof the shaft are carried upwardly directed rack bars 19 which engagewith pinions' 20 mounted on short spindles 21 extending from quadrants22 permanently secured at 23 to the main frame forwardly.

onthe spindles 21' and secured to the pinions 20; Theleversare eachsupplied with theusual'handlatch-26 and detent 27 which operate over thequadrant; It is to be noticedthattheends of the main frame and the innerfaces of the standards 7 and 8 arecut away at 28 to'allow the-rack'ba'rsto i 24: are rollers holding: the rack bars against the pmlons; and 25are levers swung swing" slightly sidewise to accommodate the slots.

29 1 is a cross shaft mounted inthe upper end? of the uprights 13 andpassingthrough the angle bars 11 and 12;

30 and 31 are angle iron bars pivotally secured at 32 to the/upper endsof the an gle bars 11 and 12 and forming in reality an upper extensionof these bars. 33is across shaft mounted'in the upper ends ofthe bars 30and 31, and 3 1, 35, and 86 are sheet metal plates secured to theinturned flanges of the angle iron bars 11 and 12, 14and 15, 30 and 31,respectively, these partsformingwhat I desire to call my adwith suitablyspaced connecting cross slats ratchet wheel.

43. Each cross slat is supplied with a set of prongs 44. A tube isinserted-on the shaft'17 between the chain wheels 37 and 38, 'which tubeserves to'reinforce the cross slats as they pass around the lower end ofthe conveyer.

46 and 47, are adjusting arms secured permanently to the sides of theangle bars 30 and 31 and having their free ends connected by cables 48to a winding shaft 49 carried by the angle bars 11 and 12.

' 50 is acrank fixed on the end of the shaft V for turning the same, and51'is a ratchet wheel on the shaft adjoining the outer face of the bar11.

52 is a pivoted ratchetengaging with'the The arms can be drawn up orreleased as will readily be seen by turning the crank so that'the upperend of the conveyer or elevator can'be raised or lowered as desired. 12'j I 1 In order to take up any slack in the chains which may appear whenthe upper end .of the conveyer is. adjusted I haverplacedtwo rockingbars 53 of channel ironcross section on the shaft 29, whichbars arefitted These rollerscarry the chains on the" ascending side of theconveyer at all times.

55 isa-d'ump' rack pivotally'secured to the rear end of the main frameat57.

f 58 is a spring catch secured to the dump rack and engageable withacross bar 59 carried by a cross beamHGO in turnsupported by the beams2and" 3. The catch holds the rack against dumping until released by; themovement of a lever61 connected to the catch bya link 62, whichlever isunder the control of the operator. The dump rack is positioned so as toreceive material deposited from the upper end oftheconveyer, and theupper end of the conveyer is arranged as already described so that itcan be raised orlowered to spread the sheavesevenly in the rack. Y 1 V63 is a counter shaft rotatably mounted in the main frame, and 64 is achain wheel keyed on the shaft and connected through a'chain 65 with achain wheel 66 located on the end of the shaft 29.

67 is a second chain wheel on the shaft 29 and it is connected through achain 68 with a chain wheel 69 on the end of the shaft 33.

The axle 5 is carried by bearing blocks 5 secured to the rear end of themain frame and the bearing blocks are partially cored out at 5 toreceive rotatably a female clutch member 70 feathered on the axle at 71and acted upon by a spiral spring 72 housed within the boxing andencircling the axle. The traction wheels are each provided with maleclutch members 73 which rotate with them and engage continuously withthe female members.

74 is a chain wheel fixed centrally on the axle and connected through achain 75 with a chain wheel 76 fixed on the shaft 63. According to thisconstruction it will be seen that as long as the machine advances thetraction wheels will rotate the axle 5 and drive the conveyer, butimmediately the machine is backed up the traction wheels will turn freeof the axle as the male member of the clutch will escape over the femalemember, the female member springing into the boxing.

, 77 is a cross bar permanently secured to the frame forward of thetraction wheels, which beam carries double trees 7 8 whereby draftanimals can be attached to the machine.

.79 is a further cross beam secured to the frame. This beam is suppliedwith the usual neck yokes 80.

What I claim as my invention is Ina sheaf loader, the combinationcomprising a main frame having an open forward end, traction wheelssupporting the main frame rearwardly, standards secured to the forwardends of the main frame and provided with arched slots, caster wheelssupporting the standards, an inclined endlessconveyer mounted on theframe and having pivoted upper and lower ends, the lower end of theconveyer being guid ed in the slots aforesaid, means for adjusting theupper end of the conveyer, means for adjusting the position of the lowerend of the conveyer in HERBERT HUN TINGDON DAVISON.
